Recognize the Causes of Roof Leaks

Leakage on the roof is one of the most disturbing residential diseases. Leaks can cause damage to the ceiling or ceiling, change the color of the wall paint, and even cause a short circuit on the electronic devices in your home. Therefore, you should call the Roofing Cape Girardeau to get the best roofing service for your home.

How to prevent the entry of rainwater through the roof and into the house? That is the main challenge of the design of the roof and the selection of cover material. Factors that causes leakage include many things, the shape of the roof, roofing materials, and other technical factors. As the owner and user, you should understand the causes of this leak, here we try to give a brief explanation for you.

The Slope and Shape of the Roof

Although it may not be directly, the shape of the roof is also a factor causing leakage in your home. Here are some of the elements that form a roof that has the potential to cause leakage.

First, the slope of the roof. Each type of roof covering or tile has different roof slope requirements or standards, for example, clay roofs should be installed with roof slopes from 30 °, while metal roofs can be installed on slower roofs starting from 5 °.

Roof or tile coverings are arranged in a stacked or stacked manner, meaning that there are gaps between the tiles which can cause water to enter when it rains. The gentle the roof is, the more open the gap is to the wind. That is, the steeper the roof is more resistant to leaking. But a roof that is too steep actually makes the meeting point between the tiles that should be interlocked because the weight itself becomes loose, and the tile can be separated or shifted from its place. Therefore, choose the type of tile in accordance with the desired slope, or vice versa, adjust the slope of the roof with the desired type of tile.

Second, the shape of the roof. The most commonly used form of roof is the saddle. Saddle or pyramid roof is a form of the roof formed by 4 or more similar sloping fields that lead to one peak. The roof of the saddle has a meeting angle between the fields of the roof, there is an outside saddle to the meeting of the roof on the outside and a saddle in the roof meeting that occurs at an inner corner. Leakage problems generally occur in the interior of the interior because this angle is the path of the rainwater flow.


Roof tiles or roofing can also cause leaks. Material or material has its own characteristics, age, as well as weather and impact resistance. Clay or ceramic roof coverings are generally prone to collisions (easily broken or cracked), roof coverings from fiber materials generally have a weakness against excessive exposure to sunlight and hot air, while metal or metal roofs have a weakness against air containing salt.

Not only on the roof covering material, but we must also be aware of the choice of roof structure materials. Miscalculation of the structure or selection of the type of roof structure can cause the roof plane to sag and the tile to move out of place.

Gutter and Rainwater Channel

One roof element that often causes leaks is gutters, rainwater channels or pipes. Rainwater gutters are generally made of lightweight and elastic materials such as PVC pipes, carpets or plastic sheeting, as well as metals such as zinc sheets. Leaks can occur due to shifting gutters due to bonds that are not strong, or damage to the gutters themselves due to material life or weather exposure. Another thing to watch out for is the collection of rubbish such as leaves and dry branches on the gutters or rainwater drainage holes, the accumulation of rubbish results in blockages in the gutters or pipes which can further lead to leakage.

Concrete Roof

The concrete roof is often the choice of home design because it is considered to have the smallest possible leak. However, this is not always true, because the concrete does not have its own material properties which, if not addressed properly, are still likely to leak. The main disadvantage of concrete is not porous concrete material, meaning that if it is not coated with a good waterproof coating then water can still penetrate or seep under it. Due to the nature of waterproofing materials that are generally elastic and not resistant to the sun’s heat, the waterproofing layer should be re-coated once every 1-2 years.
